Like letters of reference indicate like parts.

The object of my invention is to improve the details of construction ofa car-door fastcner patented to me August 7,1883, and numbered 282,598,and also the door patented to me July 10, 1883, and numbered 281,170.

I make no claim in this application to the car-door mechanism hereinshown, as it forms the subject of claims in another application filed ofeven date with this, and numbered 123,319.

a is the lower and b the upper part of my door provided with my improvedlock. 0 is a flat bar of iron, fastened to the side of the car under theeaves, so as to form a sliding track for the hooks g. The bar 0 isfastened to the car with screws of which the head is flush with the faceof the bar 0, and which pass through a post or bracket, 0, into the wallof the car. This construction of track 0 permits the use of a lighterbar for track than can be made of a round rod, as it can only besupported at its ends, and this also permits the use of a sliding hook,g, which cannot be removed, and will not interfere with the posts a.

To the lowerend of the hook g is hinged a bell-crank lever, 9, throughthe lower end of which passes a rod, 1?, which forms, with the eye '6ol' the strap 1', a hinge upon which hangs the strap 0', which ispermanently fastened to the door I). Said straps overlap the door a. tonear its lower end, so as to bring the lever i within easy reach, but isnot fastened thereto. The strap i may be either formed into one part ofahinge or, preferably, bolted to a piece, 0, which is formed into onepart of a hinge. it.

To the lower door is bolted a strap, p, which has its upper end formedint-o the opposite part of a hinge, IE, to fit into In", and its lowerend is formed into a. pin, 1), which fits into a staple or eye-bolt, q,in the side of the car. The parts 0 and p are united by the pins a awhich form part of a rod, a, and the part 12 forms the end of a hook,into which its end of the rod n is formed, which is kept in its place bythe lug 75 through which the rod 12 passes, and the pin a is kept fromfalling out by not being withdrawn from the part If, as shown in Fig. 1.By pushing said rod back and forth the pins or 'n" unite or disconnectthe parts p and o, and thus unite or separate the parts ct and b of thedoor. The rod n has a knob, a", which forms a handle and also a stop,which strikes against the strap 12, which prevents its moving too far.hen the doors are separated, by moving the rod or, its hooked end passesinto a staple, of, and thus locks the lower door so that it cannot belifted out of its place.

Through the bearing it passes a shaft, 2, to

To the outside of the hook j is fixed a pin, j, so as to form acrank-pin, upon which plays the lower end of the-rod f. The upper end ofsaid rod is provided with a thread, f ,which v screws into a nut, j,which forms a part of the hanger f The hanger f is united to the .hook gby a hinge-joint, f and pin 9.

To the center of the shaft 6 is attached a strap, 3, between the ends ofwhich plays a lever, 13, in a plane which passes through the lever andaxis of the shaft 6, and by which said shaft is turned and the hooks jcaught upon or released from the pins j.

To the lower and front corner of the upper part of the door I) isattached a spur, b, which extends inward from the inside face of thedoor. Said spur rests upon the top of the door a when the upper door isopened, and thereby holds the lower door from being lifted out and theupper door from swinging out at its lower end, the top of the lower-doorbeing beveled inward and downward, as shown, to hold the upper door fromswinging out when opened, its lower end fitting upon that of the lowerdoor. To the center 'of the lower door is attached a hook, h, of whichthe horizontal part h is long enough to let the lower end of the doorswing out so as to slide back clear from the side of the car when theparth strikes againstthe inside of the guide or projection h, whichextends below the bottom of the car so as to form a guide for said hook.

To the side of the car are attached steps or lugs m, upon which the doorrests when opened, and which keep it in place, ready to be closed.

To the dooris attached a hook, t, into which the lever 25 passes to holdthe parts in place, and where it may be locked or otherwise secured.

- The part f, as shown in Figs. 4 and 5, passes into the wall of the carwhen the door is closed, and for that purpose a place is cut out of thewall for it.

To open the entire door, pull down the lever it into the dottedposition, as shown in Fig. 2. This motion will pull down the rod f an dthrow the crank from the position shown in Fig. 4 to that shown in Fig.5, and with it the upper end of the door will pass both outward andupward and lift the lower end of the door out of its stops, so that itmay be swung out, so that the parts 71/ It will strike when it may beshoved back or open.

To open the upper door only, pull the pins 92 02 out of the hinges, andthen operate the lever and other parts, as before. By separating thehinges, the hooked end of the rod nwill pass into the staple of and holdthelower door from being lifted up.

To release the lower end of the door so that it may swing out, as shownin the dotted outline in Fig. 5, bring the lever t back to its originalposition after If and h are in contact. 7 This will throw It below h,and the door will then swing out, as shown. The beveled side of thedoor-frameis shown by a, and the stop against which the doorstrikes inclosing by a.

XVhat I claim is 1. In a car-door lock, the bar a and hook 9,

provided with swinging bell-crank gflwhereof the lower and outer end ishinged to the upper part of a door, and its inner end connected to ahinged and adjustable rod, f, of which the lower end is attached to acrank operated by a lever, 13, connected to said crank, and the lowerend of said door is held by stops, substantially as specified. 2. Incombination with the separable doors a b, the parts 1) r, staple q,bell-crank and sliding hook g, hinged and adjustable rod f, crankj, hookj, pinj, shaft 0, and lever 25, substantially as specified. v I

3. In a sliding and separable door, a locking mechanism consisting ofthe separablyhinged parts p r, passing into staples qbelow, and hingedto bell-crank levers above, to the inner end of which is attached anadjustable and hinged rod, f, connecting with a crank, j, and hook j,catching on pin 7', operated by a lever, t, substantially as specified.

4. In a car-door lock, the mechanism for both lifting and throwing thedoor outward from its frame, in combination with a hinged lever, 26, ona shaft, 0, operating in a plane through said lever and the axis of theshaft, substantially as specified.
